A short review of the optical and far-infrared measurements on MgB 2 is given. Multiband and multigap effects are analyzed by comparing optical properties with other experiments and ab initio calculations. The covered topics are: the plasma frequency, electron-phonon interaction, impurity scattering
The 10 and 300 K Raman spectra of CdBr, and CdClz have been investigated at high sensitivity. While some of the new lines are of second-order origin, others are associated with local modes of halogen impurities. Lines at 107 and 170 cm-' in CdBr, are assigned to the EJTO) and A,,(TO) lattice modes r
